` The present invention relates to heat resisting trouser legs.

More particularly the present invention relates to wearing apparel forworkers who are subjected to the dangers incident to hot splashing metalor the i like. An example of such a worker is a metal molder who mustWork in the vicinity of hot molten material which hot material is likelyto splash. Garments such as asbestos leggings, overalls and the likehave been proposed, but so far as applicant is aware such garments havebeen objected to by the Workers because they are heavy, interfere withthe movements of the wearer, and/or require the worker to change hisclothes at his place of work. So objectionable have these garments beento the workers that they have avoided the use thereof to the jeopardy oftheir own safety.

An object of the present invention is to provide a garment which may bepart of the ordinary trousers worn by a worker and will not interferewith his comfort or movements.

A further object is to provide a garment which by a simple sewingoperation or the like may be substituted for the bottom portion of theordinary trouser leg i and which will effectually resist splashes of hotmolten material.

A further object is to provide a trouser leg having a portion thereofcomposed of heat resisting l material, which trouser leg will form nopockets for catching globules of molten material and which will notinterfere with the movements of the wearer thereof.

A further object is to provide an improved pro- 5 tective device forthose who must be in the vicinity of splashing molten material, whichwill be convenient and agreeable to the wearer.

A further object is to provide an improved protective device which is soinconspicuous that the .l wearer will have no objection to wearing it onthe streets while en route between his home and his place of work andreturn.

Further objects will appear as the description proceeds.

5 Referring to the drawing- Figure l is a view of the legs of a wearerof one embodiment of the present invention;

Figure 2 is a sectional view, on an enlarged scale, of certain detailsof construction; and

0 Figure 3 is a View similar to Figure 2 but showing a modification.

The numerals Il'I-Ill represent trouser legs of which the upper portionsI I-II are of the ordinary material of which trousers are commonly Thelower portions of the trouser legs Ill- Ill `are tubular members I2--I2secured to the upper portions II-II. Said tubular -members I2-I2 may bemade of asbestos or other material having the advantage of resistingheat. As shown in Figure 2, each tubular portion I2 may be provided atits bottom with an inturned hem I3. Secured to the top of each tubularmember l2 is a flexible fabric tubular member I4 having its lower edgeinwardly turned to provide the hem I5. The upper extremity of thetubular member I2 is disposed inwardly of the hem I5. The upperextremity of the tubular portion I4 is disposed inside the upper portionII of the corresponding trouser leg. Preferably the lower extremity ofthe upper portion II is turned inwardly to provide the hem I6. The upperportion II of the trousers, the tubular portion I4 and the tubularportion I2 may be united by stitches.

The upper extremity of the tubular portion I2 of heat resisting materialmay stop just below the knee of the wearer. Inasmuch as the tubularportion I4 is of flexible material, and inasmuch as the upper portion II is of the ordinary material of which trousers are made, there will beno interference with the knee action of the wearer. The flexible tubularportion I4 may be united to the tubular portion I2 at the factory andsaid tubular portions I2 and I4 may be sold as a unit. A housewifeequipped with needle and thread may sew the tubular portion I4 to theupper portion II of the trouser leg. In many instances, of course,trousers will be utilized which have been worn to such an extent thatthe wearers do not desire them any longer for regular street Wear. Thebottom portions of such trousers will be removed and the protectivetubular portions substituted therefor.

The embodiment shown in Figure 3 omits the flexible tubular portion I4,the heat resisting tubular portion I2 being united directly to the upperportion II of the trouser leg, preferably at a region just below theknee of the wearer. The construction of Figure 3 does not have theadvantage of the construction shown in Figure 2 in that the housewifemay attach the protective portions I2 by sewing only through exiblematerial. However, the construction shown in Fig,- ure 3 presents novery serious difliculties to the housewife in sewing the portion I2 inplace.

rll'he described embodiments of the present invention do not present anunsightly appearance and Workers do not object to Wearing them fromtheir homes to their places of employment and back to their homes.Inasmuch as the workmen may at their homes don the trousers includingthe protective portions and do not have to change at their places ofemployment, and inasmuch as said trousers are neither uncomfortable norinconvenient, they are perfectly willing to wear the protective devices.

Inasmuch as the tubular portions l2 need not be bound tightly to thelegs or ankles of the wearer, he gets plenty of ventilation inside theprotective members, and therefore he does not object on that score. Ofcourse, the worker may use heat resisting shoes such as molders are wellacquainted with. It should be noted that the present invention forms noupwardly presented pockets or ledges upon which globules of hot moltenmaterial may lodge.

Though certain preferred embodiments of the present invention have beendescribed in detail, many modications will occur to those skilled in theart. It is intended to cover all such modifications that fall within thescope of the appended claims.

What is claimed is:

l. A pair of trousers comprising, in combination, an upper leg portionof cloth and a tubular lower leg portion, said lower leg portionincluding a portion of heat resisting material, the upper extremity ofsaid heat resisting portion being suciently low to avoid interferencewith the knee action of the wearer of said trousers, the upper extremityof said tubular lower leg portion being disposed within said upper legportion, said tubular lower leg portion being free of upwardly presentedledges upon which globules of hot material may lodge and beingsufliciently large in diameter to permit uninterrupted Ventilationtherethrough along the leg of the wearer.

2. A pair of trousers comprising, in combination, an upper leg portionof cloth and a tubular lower leg portion, said lower leg portionincluding an asbestos portion, the upper extremity of said tubular lowerleg portion being disposed within said upper leg portion and beingsuiciently low to avoid interference with the knee action of the wearerof said trousers, said tubular lower leg portion being free of upwardlypresented ledges upon which globules of hot material may lodge and beingsufficiently large in diameter to permit uninterrupted ventilationtherethrough along the leg of the wearer.
